These are three good books for learning Arabic Language for the non-native speakers. But we should pay your attention that they are for who has slightly good knowledge about Arabic and how to pronounce it. We don't claim that you can consider them as an alternative to a teacher but they are good step for who wants to be excellent at Arabic. With these books, there is an Arabic-English glossary confined to the words mentioned in these books, and the author shows in its introduction how to find any word.
An excellent book for non-Muslims explaining various aspects of Islam.

The Book Of Prayer: Salaat (Prayer) is one of the main obligations which Allah (subhanahu wa ta’ala) has ordained on His servants. It is the first act of worship decreed on the Muslim Nation (Ummah) by Allah (subhanahu wa ta’ala) and was ordained on the night of the Prophet’s (peace be upon him) ascension to the seven heavens. It is the second of the five pillars of Islam after the proclamation of the “Shahada” (the words of witness).
